EMF

Electromotoric force (electric/mechanic transformer)  Description The Rotational EMF (or EMF) component transforms electrical energy into rotational mechanical energy. It is used as a basic building block for an electrical motor. The mechanical connector, flange, can be connected to rotational mechanical components. Equations $i={i}_{p}=-{i}_{n}$ $v={v}_{p}-{v}_{n}=kw$ $w=\stackrel{.}{\mathrm{\phi }}$ $\mathrm{\phi }={\mathrm{\phi }}_{\mathrm{flange}}-{\mathrm{\phi }}_{\mathrm{internal}}$ ${\mathrm{\tau }}_{\mathrm{flange}}=-ki$ Variables
